To all whom it may concern Be it known that I, GEORGE W; SWIFT, J r a citizen of the United States, residing at Bordentown, in the .county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Corrugating-Machines, 'of which the following is a specification.

The-object of this invention is to provide an improved machine for making corrugated paper-board, and particularly that class in which but one facing sheet is employed.

Another object is to provide in such a machine an improved mounting for members operative'to strip the corrugated sheet from one of the corrugating rolls to which it has a tendency to cling, said mounting being automatically adjustable to accord with changes inthe length of said roll due to expansion and contraction.

Still another object is to provide an improved steam manifold With automatic takeup means operative to maintain steam-tight joints with the corrugating rolls as they expand and contract with changes in temperature. j

-A further objectis to provide means for supporting the corrugating rolls ofthe machine intermediate their ends to prevent their warping under the strains coincident with pressing paper between them, and Without hindrance to the passage of webs of said paper therethrough.

And a further object is to provide an im'- proved mechanism for maintaining the glue roll of the machine revolving in both ex-' treme operative and inoperative positions together with m'eansto'shift the said roll from one of said positions into the other.

Additional objects and details of the construction of a machine comprising the preferred embodiment of this invention are fully described in the following specifica-.

tion, when read in conjunction with them:- companying drawings in which latter Figure 1 is a side elevation of the machine, with the steam manifold removed; Fig. 2 isa front elevation of the greater position of said machine; Fig. 3; is a vertical section on the line 33 of F1g. 2; Fig. 4 is a section on the line 44 of Fig. 2; Fig. 5 is a section on the line 5'5 of Fig. 2; Fig. 6 is a section on the line.66 of Fig. 2; Fig. 7 is a detail section of one of the socketed caps for the rolls; Fig.

8 is a detail view of one o'flthe fittings designed to cooperate with sald caps; 9

is a detail. view of a spring-adjusting collar for said steam fittings; Fig. 10 is a fragmentaryelevationshowing the correlation between the corrugating rolls and stripping members; F ig. 11 is an end view of one of said members and its floating mounting; Fig. 12 is a side view of the same; Fig. 13 is a side-view of one of the glue-roll stripping members; Fig. 14 is a side elevation of the glue roll mounting; Fig. 15 is a section on the line 15-15 of Fig. 14; and Fig. 16 is a vertical section of the glue tank.

Referring to Figs. 1 and 2 of the draw- I ings the preferred form in which the invention is embodied comprises a pair of upright side frames 1 and 2 provided at their lip-1 permost portions with adjustable bearings 3, upon and between which is revolubly mounteda shaft 4, carrying a roll 5 of paper,

from which a continuous Web 6 passes down-. 'wardly over rollers 7 adjustably mounted by means of brackets 8 upon said frames.

In each of the said side frames is pro- Vided a pair of guides 9 between which are slidably mounted three journal boxes 10 in the two upper of which are rotatably mounted the tubular shafts 11 carrying corrugating rolls 12-and 13, while the shaft 14 mounted within the lowermost of said boxes carries a smooth roll 15., Of the corrugating rolls the upper is circumferentially grooved at spaced intervals 16 for the purpose hereinafter described, while the characteristic longitudinal grooves of.the lower one are continuous throughout the entire .length thereof.

Referring to Figs. 3 and 4,. as well as to those above mentionedyeach of the central journal boxes is secured by a bolt 17 to said guides at a given elevation, while between the upper and lowermost pairs of said boxes extend trusses 18',- carrying brackets 19, which in turn revolubly support rollers 20 and 21, the former being corrugated and two in number while the latter are of the same number but smooth,said rollers evenly face 37, with while of each of the trusses is attained by means of bolts 25 passing through and in threaded entral portions of the adjacent corrugated and smooth rolls respectively. Said idlers when desired may also be adjusted with respect to the adjacent trusses by means of threaded pins 28 and lock nuts 29, after the adjustment of which the respective plates 19 are secured in fixed position by bolts 30.

Each of the corrugated and smooth rolls is hollow throughout its 'fullextent while secured in threaded engagement upon and substantially inclosing the ends thereof are caps (Fig. 7), each being-provided centrally with an aperture 86 terminating nwardly in an enlarge ncave bearing surtter 'slidably cocperates the enlarged convex-head 38, of a tube 39 8),

ed to be securedin a given position by means of a .bolt 42 and provided in its oppos te faces with spiralbearing surfaces-43,:against either of which may press a coil sprung; which at its opposite cooperates WVlth the recessed washerft5, 1n turn slidablfylem I *pfi stripp'ing members 70, andis forced to v cling to the alternatingvridgesand grooves 40'is gaging'the t m t urf f th a adjacent to the tub 3 I Extending from eac of-the elbo, a tubeAS which at its opposite end is secured in threaded relation with plate 19, in turn bolted to one vertical side 50 of a hollow steam trap 51 and in alinement wit-ban enlarged opening 52, leading through. Said trap'isprovided with a vertically extending wall or partition 53, Which separates from the main portion thereof an elongated, relatively slender drainage compartment, 54, from the lowermost end of which leads'adrain ipe 55, while into-the apertures 56 through saidpartition aresecured relatively small tubes 57 in alinement with the apertures 52 andextending therethrough and thence through each of the respective pipes' 48, and connected by elbows 58 (within the elbow 40) with tubes 59, leading through the respective tubes 39 and caps 35'into the large rolls and to the farther end thereof, whence the former are bent downwardly to points closely adjacent to the lower inner surfaces of the said rolls.

With thisconstruction live: steam is led into the trap 51 by'means of a pipe 60',

whence it passes by means of the tubes v 18 to the opposite end of which secured an elbow Slidably mounted upon said tube is ,asleeve 4:1 (Fig. 9); adapt:

and 39 into each of the said rolls, where it tends to wear the same, any desired quantity oftlubricating oil may be injected into said live steam by means ofan oil cup 62, leading into the trap 51-, said oil being carried by the steam intothe respective rolls where a considerable portion of the former is deposited within the groove 63 "of the cap 35 or in other ways is made available for lubricating the surfaces previously referred to.

f. Asthe web 6, of paper from the roll 5, passes between the frames 1 and 2, it comes into contact with the upper apertured surface of a pipe 64, into which steam is led by means of small pipe 65., which latter is also apertured to permit the escape of steam therefrom. In this manner. the said webis 'moistenedby'means of steam being directed against it, .when the latter condenses and operates tolessen the stiffness vo'fthe former,

said'web then passing through an elongated I aperture 66, in an angular guide 67, which is in turn secured at its ends by bolt 68 to adjacent portions of said frames. The web then continues its coursepassing between the corrugated rolls where the ridges ,of one press it into the oppositely positioned grooves of the other, said weblbeing sepa- Trated from, or prevented,. from adhering to, the surface of the uppermost roll by means of themiddle roll until it comes into con "tact withjthe surface 71 of a glue roll 72. The corrugated web thence con- .tmues around the said middle roll, being prevented from adhering to the roll 72, by means of strippers 73, until there is' pressed against'the outer lued ridges of said web provided a fixed rod '78, uponwhich are sevided with-recesses 81', extending inwardly a facing sheet 75:, y *meansof the' smooth I roll 15. 1 "j Referring to Figs. 10,--1-1'-and12, there is from one face thereof. Surrounding and,

slidably mounted upon said rod are -sleeves 82, provided with" pins 83, slidably posi- -tioned-within the aperture 81, and herein lies onejofjtheprincipal advantages of this construction} Each of said last-named sleeves is provided integrally with a "shoulpointed concave strippers:70, one end of each of which slides Within one of the grooves 16 of the roll 12, and by virtue of its being mounted movably upon the rod 78,- it can der 84, to which is secured one of the double readily assume any position longitudinally thereof upon the expansion or contraction of said roll with the injection of steam thereinto, .or removal therefrom. Each of the strippers 7 3, on the other hand is fixedly secured by suitable means to one wall 85, of a glue reservoir 86, and has one of its ends 73' 'so positioned as toslidably enter one of the circumferential grooves 87 within the outer surface of the glue roll 72.

' The arrangement employed for gluing the outer ridges of the corrugatedpaper comprises the roll 72, hereinbefore described, secured upon a shaft 90 revolubly mounted in bearings 91, and carrying a gear wheel92,

said bearings being secured in any suitable manner. to a frame 93, inturn. mounted to energy (not shown and drives the smooth roll 15 by coiiperation with the gear 97 thereon. When on the other hand operation of the function of the glue roll is not deposition said roll is revolved by its respective gear meshing with a pinion 99, in turn driven by pinion 100, secured to the same shaft with a sprocket wheel 101, connected sired, the frame 93 carrying the same is moved to the rear of the track 94 by means of any suitable formof lever and link '98 and98, respectively, where in said rearmost by sprocket chain 102, or other suitable means of power transmission, to a gear or. pulley 103, which latter is secured to a shaft 104, actuated by agear 105, meshing with the gear 96. The glue reservoir 86 is provided with a drain outlet 107, and the frame 93 which carries the glue roll has mounted thereon a bracket 108 upon which is mount ed a. suitable means 109 for wiping all but the desired amount of glue from said roll.

The construction of the. machine thus described-shows a greatly increased efficiency over those formerly employed of acorresponding size, and in addition thereto presents certain novel features whichit is desired to protect individually and col ec-' tively, among other things there being the.

automatically adjustable stripping members adapted to take up positions with respect to the corrugating. roll immediately-upon any change in the temperature thereofythe new construction of the Steam manifold for automatic adjustment with changes in temperature of the several rolls; the provision for moistening the paper web as it passes into the machine; the improved mounting for the 'maintain a rectilinear position of glue roll; the means preventing a bending of the longitudinal :axes of the several rolls as paper is corrugated /therebetween; and other improvements over, the art as hereinbefore described and as hereinafter claimed. r r Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is: r
